Is he playing me? :(

Ive been with this guy for 2yrs now, he hasnt made us official in public, nor has he asked me to be his gf, but he tells me im like his gf, and he claims to be committed to me. From the start to now, weve been having problems with him following single, local women on fbook. And him posting single/lonely posts on his page. We also argue about when will he make me official. He told me he hasnt made us official, because i am insecure with him following girls on fbook, which tells him i dont trust him. Now, im only insecure, cause he told me he only follow girls hes really attracted to, and he has told me he liked most of them. And lied to me that hes stopped after he met me, he said he only did it cause he was single and looking. But ive been catching him following one after another til this day. Still lying about it, trying to make me the bad guy cause i went thru his phone. Also, he hasnt wanted sex for mths now, always rejecting me everytime. I crave for it dearly, but he doesnt care. He did admitted to masturbating to fbook girls instead of watching porn before he met me. He used to wants sex everyday, or would want a bj or handjob when im on my period. Now its nonexistent, now hed just move my hand away. Ive talked to him about all this, and he doesnt have a straight answer. He never wants to have a serious talk w me. He says hes tired of having to clean up after sex thats why he stop wanting it. He told me to be patient and let time do its thing with us being official.
